The action of Pokémon Scarlet and Violet takes place in the Pale region, the first truly open world in the Pokémon series.
This provides a sufficient amount of actions to perform and catch Pokémon.
Nevertheless, post-game content will force devoted fans to return, especially to Hyper Train of their Pokémon for TERM RAIDS and competitions.
One of the items that will help in this is the gold lids for bottles that can make you think about how to get gold lids for bottles in Pokémon Scarlet and Violet.

where to get the gold lids from the bottles in Pokémon Scarlet & Violet

There are only two ways to get gold covers from bottles in Pokémon Scarlet and Violet.
You can get them as a reward from the Tournament of the ACS Academy or purchase them at an auction in the city of Porto Marinade.
Both of these methods depend on good luck, since you do not guarantee that you will receive them at the ACE Academy tournament, and also does not guarantee that they will be auctioned at Porto Marinade.

How

Golden covers from bottles are even more rare than conventional lids from bottles, so you probably will have to pass the Ace Academy Tournament several times before you get it.

In the same way, they do not appear too often at auctions, and when they appear, they are absurdly expensive.
Therefore, you will need to bring a lot of designs to buy them.
Despite this, the golden lids for the bottles are worth it, since they raise all the IV Pokémon.
Conventional covers from bottles increase only one IV, so these more rare lids from bottles will significantly improve the speed with which you train the IV of your Pokémon.
